FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 665,887, dated January 15, 1901. Application tiled March 9, 1900. Saris-1N0. 8,090. No model.)

To all 1071 0111 it may (om-wra- Be it known that l, (Cit-mines ll. Ennniya citizen of the United States, residingal. Somervillej -jinthe county of Middlescx and State of Massachusetts, have in vented new and useful Improvements in Flushing Apparatus, of which the following is a specification.

.My invention relates to flushingapparatus for water-closets and the like, one object of the same being to simplify and otherwise improve apparatus of this kind which involves the employment oftwo closed tanks, one of which is filled while the other is boingemptied and stores up within it compressed air which is utilized in discharging the water therefrom upon the next operation of the valve which controls the flow to the closet-bowl.

A further object of the invention is to provide an improved construction and method of operation of the controlling-valve fOblZ-llf? inlet and discharge of the water.

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be defined in the'claims.

In the drawings, forming a part-oi this s ecification Fi- 'ure 1 isan elevation rartl Y in section, illustrative of myinvention. Fig.

.2'is a longitudinalsectional view of the valve, xi'an'd Fig. 3 is a cross-section of the same.

-ter is discharged for the .Like reference-numerals indieatelike parts in the different views.

In carrying out my water-tan ks 1 and 2, preferably located side by side, supported upon a shelf or bracket 3 and closed at all points except their lower ends, through which the water is admitted fosthe pur'pose'of filling them and from which the wa purpose of emptying them. Leading from the lower end of the tank 1 and communicating with the inside thereof is a pipe 4, and leading from the lowerend of the tank 2 and communicating with the in-' terior thereof is a pipe 5. At the juncture of the pipes 4 and 5 is a valve-casing G, into the upper end of which leads the supply-pipe 7 and from the lower end of which leads discharge-pipe 8, the lattercominunicating with the closet-bowl or other device which is to be flushed out by the apparatus. Fitting with- 50, in the casing 6 is a rotary valve 9, comprising apent ral web 10, a-conical head 11 at one end, and a similarhead 12 at the other end.

invention Iemploytwo' The heads 11 and 12 are circularin cross-scetion and are maintained in close contact with 12 in ciosccontactwith their respective seats.

As the valve or its scat wears the inequalities will be taken up oi compensated for by the action ofthcspring l3. Leakagcin the valve is therefore p:cvented. The casing 6 is formed on one sidewith an overhanging lug or projection 18, which has two engaging portions and constitutes a double stop or check, as .will hereinafter appear; The head 12 of the valve 9 is extended outside the casing 6 and is provided with'a series, preferably four, 7

ol ratchet-teeth 19, the'sanie being located directly beneath the overhanging lug 18. Se cured in -1he outer end of the head 12 is a spindle 20, on which is mounted an operating-lever 21, having a spring-actuated pawl .22 thereon, which is adapted to engage the ratchet-teeth 19 when the lever is moved in one directionand to ride over said ratchetteeth when the lever is movedin the opposite direction. The lower arm of the lever 21 is longer than the upper arm thereof and is provided with a ball or weight 23, which tends to return the lever by gravity to its normal positioi after the extreme lower end of the lever 21 is attached an operating cord or chain 24; which passes up and around the pulleys 25 26 and has a handle 27 upon its lower end. 1

The operation of the device, constructed as above described, is as follows: With the valve 9 in the position in which it is shown in Fig. 3 of thedrawings the passage is open between the pipes 7 and 5 to the inside of the tank 2, and through the pipes 4 and 8 from the tank 1 to the closet-bowl or other device to be flushed. The tank 1 is therefore discharging or has discharged its contents into the bowl, whereas the tank 2 is beingfilled or has been filled with water from the supply-pipe 7. As the water enters the tank-'2 at its lower end it has on'ceb'een actuated. To'

it rises therein and. compresses the air in said tank at the upper end thereof until the pressure of said air and of the head of water is equal. Upon now pulling down the handle 27, attached to the cord or chain 24, the lower arm of the lever 21 is elevated until it strikes one side of the stop 18, and through the engagement of they pawl 22 on said lever with one of the ratchet-teeth 19 on the end of the valve .9 said valve is turned a one-quarter revolution. Further movement than this at a single stroke of the operating-lever is prevented by the engagement of said lever with the stop or check 18, formed on the stationary valve-casing 6. As soon as the hand is removed from the handle 27 the lever 21 returns to its normal position by gravity, the pawl 22 riding over the inclined walls between two adjacent ratchet-teeth 19 and the short arm ot the leveiggl engaging the opposite side of the "stop 18. When the valve has been turned a one-quarter revolution by the action described, the web 10 thereof lies at right angles to'the position shown in Fig. 3 of the drawings, and the passage from the pipe 5 to the pipe 8 is opened and the tank 2 is free to discharge its contents into the closet-howl to be flushed, the flow of water from said tank to said bowl being caused by the weight of saidwa'ter assisted or augmented by the ac tion of the compressed air at the upper end of said tank. At the same time the passage through pipes 4 and 8 .is closed and the passage through the pipes 7 and 4 is opened. Water from the source of supply can therefore flow into the tank 1, as heretofore described with reference to tank 2. It will thus be seen that as one tank is discharging its contents into the bowl or other device to be flushed the otheris being filled with water from the source of supply. It will also be observed that the movement of the valve 9 during the successive operations of the lever 21 is a continuous rotary movement and that all wear between the valve and its seat will be takenup by the spring 13. It will be noted,

further, that it is impossible to turn the valve 9 through an arc of more than ninety degrees by a single operation of the lever 21 by reason of the engagement of said lever with the op-- posite sides of the double stop or check 18.

Having now described my invention, what I claimas new, and desire to secure by Letters Patent, is-

1. In a flushing device, the combination of 5 two tanks, pipes leading into the lower ends of the same,a valve-casing at the juncture of said pipes, a projecting lug thereon constitu ting a double stop, supply and discharge pipes leading into said/casing, a rotary valve controlling the passage from said supply-pipe to said tanks and fronts-aid tanks-t0 said discharge-pipe, and a lever for operating said valve adapted to engage'said stop on opposite sides for limiting its movements in both directions, as and for the purpose setforth. 2. In a flushing device, the combination "with two tanks, pipes leading into the lower ends of the same, a valve-casing at the juncture of said pipes, a projecting lug on said casing having two engaging portions constituting a double stop, supply and discharge pipes leading into said casing, a rotary valve controlling the passage from said supply-pipe to said tanks and from said tanks to said dis- 7 5 charge-pipe, thesaid valve having one end projecting from said casing and provided with ratchet-teeth, a spindle fitting a socket in said valve, an operating-lever for said valve mounted on said spindle, and a spring-actuated pawl on said lever adapted to engage said ratchet-teeth, the said lever having its movements in both directions limited by its engagement with opposite sides of said stop, as and'for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. A
